I've just released a new version of my 3D modeler, JPatch.
JPatch is a spline based 3D modeling tool. It allows to create 3D models
which can be rendered with POV-Ray or RenderMan compatible renderers
(e.g. Aqsis).
It is free software (open source); you can redistribute it and/or modify
it under the terms of the GNU General Public License.
JPatch is work in progress. The current version supports modeling only,
but I'm working on character animation features for future releases.
JPatch is written in Java, so it should run on every platform with a
Java Runtime Environment (JRE) 1.4 or later installed, including
Microsoft Windows and Linux.
